that button turns the sensors for your alarm on and off I'm pretty sure its in the owners manual.

but I also have another questions does anyone with a b5 have the compartment under the steering wheel for the owner's manual? my stealershup swears up and down that i have it but i was upside down in my drivers seat the other day looking for this thing and its no where to be found... gotta love secret hidden treasure like the third center sun visor.

 

Diddo, those Germans think of everything!

 

i found this late too, was cleaning my car and i thought the roof (SKY) was falling when i accidentally hit it when i was cleaning the headliner. [&o]

 

lol.. i just went outside to check if i had one, and i do! ..after wondering what it was for it hit me, that ti blocks the orange sunroof lights from going into your mirrior at night. I always found this annoying but now i bet its not there with that down. That is my guess.[8D]

 

yeah yeah i use the little flap thing too, it works well, you dont notice it at first a lot tho, took me a month
